SMOKING-PIPE.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed August 29, 1912. Serial No. 717,737.

To all whom it may concern:

Be it known that I, JOHN D. MAIER, a citizen of the United States, residing at Charlestown, in the county of Cecil and State of -Maryland, have invented new and useful Improvements in Smoking-Pipes, of which the following is a specification.

This invention relates to smoking pipes and one of the principal objects of the invention is to provide a simple and efficient pipe which may be readily cleaned and which will give the smoker a cool, dry smoke.

A further object of the invention is to provide a pipe with a cleaning device arranged in the stummel in such a manner that a relatively short pipe may be used and a long smoke passage produced.

A further object of the invention is the provision of means for removably connecting the stummel and smoke tube to the bowl so that it may be readily removed for cleaning or for replacement of parts.

Further objects of this invention will ap pear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure 1 is a side elevation. Fig. 2 is a longitudinal sectional view. Fig. 3 is a section of the smoke channel removed. Fig. 4 is an elevation of the core removed. Fig. 5 is a sectional view of the stummel tube removed from the bowl.

the terminal end thereof beaded, as shown \at '8, for a purpose to be hereinafter described. The stub stummel t has projecting from diametrically opposite points, suitable pins 9'which are adapted to engage in the bayonet joints 10 formed in the stummel tube 11. This stummel tube is preferably formed of suitably ornamented metal and has a plurality of fine perforations 12 therein so as to permit the radiated heat from the tube 6 to escape. The'tube 11 is slightly tapered throughout its length and the outer end thereof is turned inwardly to produce a retaining flange 13 which engages the bead 8 and holds the smoke tube in position in the bore 3.

Removably mounted in the smoke tube 6 is a cleaning core 14 having a spiral semielliptical groove 15 formed throughout its length. This core completely fits the tube 6 and causes the smoke to travel a circuitous or spiral path through the smoke tube. The core is provided with an extension 16 having a channel 17 which passes out of the extension and communicates with the spiral groove, as shown at 18. Mounted on this extension is a mouth piece 19 which is tapered, as shown at 20, to fit the flared end 7 of the tube 6.

What is claimed is:

1. In a pipe, a bowl having a stummel, a smoke tube fitted in the stummel, and a perforated casing removably secured to the stummel and engaged over the end of the smoke tube for holding the same in engagement with the stummel.

2. In a pipe, a bowl having a stummel, a smoke tube fitted in the stummel, a perforated casing having an inwardly turned flange to engage over the edge of the smoke tube for holding the latter in engagement with the stummel, and a detachable locking conlnection between the casing and the stumme 3. In a pipe, a bowl having a stummel, a smoke tube removably engaged in the stummel, a perforated casing removably connected to the stummel and. engaged over the end of the smoke tube for holding the smoke tube in the stummel, a spirally grooved core arranged in the smoke tube and having a channeled extension and a mouth piece having a socket to fit the extension, said mouth piece being pivoted tofit within the smoke tube.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN D. MAIER.
